I always thought about this. What if in all these war torn areas instead of becoming militarily involved we just started doing massive aerial drops of food, water, possibly some simple tech for getting online, maybe some power generators. Everything dropped would have the american flag plastered all over it. Over time imagine the amount of good will that would begin to foster with local populations. If you did it long enough and on a large enough scale, whenever some fundamentalist comes along and starts spouting about America being the great Satan how many would get behind him then. And I bet it would cost a lot less than direct military action anyway.
